as an administrator, I want to use less resources which means just text (a summary of content--no bbcode/attachments) ... and direct readers to parsed content / comments ... content displays faster and less resources are used

as the blog owner and/or reader, I would like to see all content (bbcode/attachments) parsed on index page ... less work -- no need to click "read more" to read entire content

You have two text areas to fill: a "teaser" that's shown on the list page and the "real" content shown together with the teaser on the page of the entry.

that's actually a good idea ... it never occurred to me to combine the summary with the content on entry page ... ahhh, a bonus as this is the writing style that I prefer ...
NOTE TO SELF: (summary) ? append to message : false;
